This invention relates to certain improve-.

ments in apparatus for generating ozone, an more partlcularl in that class of such a paratus wherein t e generation is effected by the formation of an electric discharge across an air chamberor passage; and the object of the invention is to provide an apparatus [of this general character of a simple. and inexpensive nature by means of which the ozone ma be generated in considerable volume an wherein means are provided for regulat ing such generation an also for regulating the su ply of the generated ozone to a patientw ere the apparatus is designed for electrotherapeutic employment.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved ozone-generating apparatus whereby ceitain important advantages are attained and the device is rendered simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth. e

The novel features of. the invention w ill be carefull defined in the claims. I

Big. 8 is a diagraphic view showing the circuit connections of the improved apparatus when designed for use with a static electrical machine as a source of su ply. vFig. 9 is a view similar to Fig. 8, but showin the circuit connections of the apparatus w on designed for employment with an alternating-current generator as a source of supply.

As shown in the views, the improved apparatus comprises a base or support, which may be of an desired construction, preferab y provided with a flat u per surface or table'l, upon which is centrail the generating-chamber, which is indicated as a whole at' 2 and comprises lower andupper parts 3 and 4, of non-conducting material of rectangular form, and between which at the angles of the rectangular berare extended posts or upri hts 5 5, thesides and ends of said casing or c amber 2 being closed by plates 6 6, of glass or other suitable material, the edge portions of which are let into the posts or uprights 5 5 and into the top and bottom plates 4.and 3, as indicated inFigs-. 3and 4 I v Within the chamber or casing 2 thus formed is provided an interior or auxiliary casing )also of rectangular construction and formed of corner posts or uprights 9 9, extended from the bottom plate 3 to the top the sides of, said interior casing being closed by means of sheets or plates 7 7, of non-conducting material, held in place in a way similar to the glass plates 6 above referred to. The ends of the interior casing also of non-conducting material, the arrangement being such that a generating chamber or compartment 10 is produced within the interior casing, chamber or compartment are formed wholly of non-conducting material.

but which is casing or chamare-similarly-closed-by end plates 88,

y arranged the Walls of which generating The dimensions of the interior casing are such that a space is produced within the easing-2 and surrounding said interior casing, as clearly shown in- Fi supply of air to sai generating chamber or rovide an air-supply pi e or conduit 1 1, a so ormed, by preference, om non-conductive and non-corrosive substance, which is extended across thespace intervening between the and Y end walls f the inner and outer, cas' 3 and 4, and for the has an end portion communicating with the f chamber or compartment by way of a central opening produced in the end wall 8 of the interior casing, the opposite end of said pipe or conduit 11 being extended through an openthe interior casing,

of the end edges 0 ing in the end plate 6 of the outer casing and being bent down outside the casing 2, as indicated at 14, and passed through the flat top plate or table 1 of the supportingbase, beneath or within which said downwardly-extended portion 14 of the air-supply pipe or conduit has connection with a blower or airforcing device 15 of any preferred kind, for the operation of which an electric motor 16 may be conveniently employed.

16 16 indicate the circuit wires or conductors for the supply of said motor 16, and

I 16 indicates a switch or controller of any preferred kind, included in the motor-circuit and preferably located upon the support or base of the apparatus in convenient position for use by the operator for controlling the motor, and thereby controllin the supply of air from the blower 15 through pi es 14 and 13 to the generating-chamber 10 o the apparatus, so that the proportions of pure and ozonized air supplied to a patient by way of the discharge devices (to be hereinafter described) may be controlled and varied at will.

The end. walls or plates 8 8 of the interior casing of the apparatus are provided with vertical grooves or channels 20, parallel with each other, but spaced apart and desi ed to receive and hold the end edge ortlons of glass partitions or plates 21 21, w 'ch are extended vertically within the generatin chamber or compartment 10from end to en thereof, as clearly seen in Figs. 3 and 4, the construction and arran ement of these plates or partitions being suc that passages 22 22 are produced between them and extended lengthwise and vertically in the chamber 10, said passages 22 22 being in communication with each other through openings 23 23 at opposite ends of the chamber and produced by notching or cuttin out the central portions the glass plates or partitions 21 21, so as to afford free circulation of air between the passages 22 22 at the end of whereat the air-supply pipe or conduit 11 is located, and also at the opposite end of said interior casing, whereat is located a discharge ipe or conduit 12 similar to the pipe or cond int 1 1 and similarly extended across the space between the mner and outer casings and passed through an opening in the plate 6 at that end of said outer casing.

In the spaces or passages 22 '22 intervening the glass partitions or plates 21 21 in.

the generating-chamber 10 are located other glass plates or non-conductin supports 24 24 of less lengths than said p ates or partitions 21 '21, the plates or-supports 24 being held in positions central between the partitions 21 21 between which they are arranged by means of grooved strips 30' 30, rested on or secured to the bottom plate 3 of the casing-2 and upper strips 27, which are rested upon the, upper edges of partitions 21 21 beyond the ends of the supportingplates 24.

The upper and lower edges of the plates 21 and 24 are centrally cut away or notched out, as seen at 31 in Fig. 4, and the lower retaining-strips 30 are transversely extended upon the bottom plate 3 across the chamber 10 in such a way as to pass through the space produced beneath the-plates 21 and 24 by such cutting away of their central lower edge portions, said retaining-strips being, however, provided with notches 29, in which the downwardly-extended end portions of the plates 24 are engaged in such a way as to securely position the said plates 24 in the passages 22 between partitions 21. The shorter supporting-plates 24 24 are of greater height than the partitions 21, so that their upper edges are caused to project above said partitions, as seen in Fig. 4, and the upper retaining-strips 27 which are rested upon the projecting ends of the partitions 21, have notches 28, as seen in Figs. 4 and 5, in which the extremities of the upwardlyextended edge portions of plates 24 are engaged to centrally position said plates 24 within the passages 22 22 of the generating-chamber 10.

25 '25 indicate terminal windings carried upon the supporting-plates 24 24, said windings being preferably of copper wire and having their turns spaced apart, as indicated in Fig. 4, and alternate windings 25 25 upon the series of plates 24 are connected in parallel with one circuit-conductor by means of a wire 26 or otherwise, while the remaining windings 25 upon the series of supportingplates 24 and which alternate in arrangement with and intervene between the first-mentioned set of windings have similar parallel circuit connections, as seen at 26, with an electrical conductor of opposite polarity to that with which the first-mentioned set of windings has connection. This arrangement of alternating sets of windings in parallel connection with electrical conductors of opposite polarity is well illustrated in the diagraphic views, Figs. 8 and 9, and it Wlll be obvious that where a supply'of electricity of sufficiently-high tension is present in the conductors with which the alternating sets of windings are connected an electrical discharge will occur between the windings of the respective sets, which discharge will. be caused to take place throu h the interven ng plates or partitions 21 an through the alr current supplied through the passages-22, 1n which the Win ozone from such air. that since the arrangement of the windings 25 as specified affords a comparatively great discharging-surface the capacity of the appadings are supported, so as to generate It will also be obvious ends, forked metal end pieces 54,

ratus for the generation of ozone is very mateiially increased. In the applaratus shown in Figs. 3 and 4, supposing t e portions of plates 24 whereon the windings are carried to have the dimensions of five by eight inches, it will be seen that a generating-surface of ten thousand running inches is thereby afi'orded, and at the same time the construction is of so compact a nature as to take up but very small space.

Outside the casing 2 the discharge-pipe 1.2.

opposite sides of the central coupling 42. The

coupling 42 is supported upon a-stem or uprlght 43, erected upon the table 1 of the supporting-base of the apparatus.

The lateral couplings 45 45 at opposite sides of the central coupling 42 are adapted for screw connection in a Well-known wa with wash-bottles 46, which are thereby et achably held in position and which may contain a suitable liquid for washing the ozonized air for removal of impurities therefrom or may, if desired, contain a medicament of any descri tion which it may be desirable to exhib1t with the ozonized air. In this latter case vaporizing or atomizing nozzles may, if desired, be employed in the wash-bottles 46.

The couplings 45 for the wash-bottles 46 have connection with pipes 47, which are extended toward opposite sides of the table 1 and have at their outer ends connection with couplings 49, secured upon the table 1, valves 48 being provided for regulating the flow of the fluid throughsaid pipes 47. The couplings 49 have nipples 50, with which are connected flexible tubes 51, the opposite ends of which have connection with other nipples 53 upon dischar e-tubes 52, -the body portions which are ormed from non-corrosive substance and which have, attheir su ported etween which is embraced a lug 55, erected upon a pivot-pin 57, held to turn or swivel in the upper end of the corresponding outer coupling 49, as clearly shown in Fig. 7, a pivot-pin being passed through the forks 54 and lug 55 in such a way that the discharge-tubes 52 are thereby permitted to be swung in various directions to accommodate various positionsof the patient to be treated. Each tube 52 has at its free end'a mouthpiece 58 for convenient inhalation by the patient of the ozonized air supplied by the tube 52. V

In the construction illustrated-in the drawings there are two of the administering-tubes 52 and mouthpieces 58; but it is evident that this number is in no way essential to m invention, since a greater number may, desired, be employed, or in some cases a single. tube and mouthpiece may be provided. Where more than one such tube and mouthpiece is employed, the valves 48 are very desirable for permitting control of the supply of ozonized air to suit the special requirements of each atient.

It wil be understood that my improved generating apparatus may be employed in connection with any suitable source of electrical supply, and I do not desire to limit myself in this respect. I In Figs. 6 and 8 I have illustrated the employment of'the apparatus in connection with a static machine of any desired type, 63 63 representing the prime conductors of the machine, which have connection, as seen at 62 62, with. condensers in the form of Leyden jars 60- 60, the dischargerods 61 61 of which may be approached or separated to regulate the intensity of the supply to the alternating sets of windings 25 in the generating-chamber ofthe apparatus.

In Fig. 9 I have illustrated the application of my improved generating apparatus for use in connection with a source of alternatingcurrent supply. In this view- 66'indicates an alternator which may bespecially installed ormay be at a power station, and indicates the circuit connections thereof which are connected with the primary of a trans 'former 64, the secondary of which has connection with the alternating sets of windings 25 in the generating chamber. With this form of supply the motor 16 for driving the blower 15 may be in circuit with the generator 66, although it is immaterial whether said blower be driven electrically or otherwise.

In case the source of supplybe a direct-current itwill be evident that a converter of any desired kind should also be in circuit with the apparatus. 4 From the above description it will be evident that the improved generating apparatus constructed according to my invention is of an extremely sim le and'inexpensive nature and is very desira le for use by reason of the increased'efliciency afforded by my improve- Y ments for the generation of ozone and also b reason of the greater convenience for use a forded by the improved construction and arrangement of the parts, and it will also be obvious from the above descri tion that the device is capable of some mo lfication without material departure from the principles and,

s irit of the invention, and for this reason 1.
